7 Claims. (01. 36-60) This invention relates to linemans pole and treeclimbers, having the usual spur or spike carried by a curving footholdand-leg shank, and the object of this invention is the production of aclimber having special construction and arrangement of parts,particularly with relation to an adjustable leg at the top of the shankadjustable to length of climbers leg and a removable spur membersuitably secured to the lower portion of the device.

The preferred form of this invention is illustrated in the accompanyingdrawing, of which Fig. 1 represents a side view of all parts assembled.Fig. 2 is a front or face view of the adjustable leg. Fig. 3 is a rearView of the leg plate. Fig. 4 is a cross-section of the flange membersor T iron forming the shank, the section being taken on the broken line4-4, of Fig. 2. Fig. 5 is a cross-section of the leg plate and slidehousing plate showing the flanged members in section therein. Fig. 6 isa front view of the pivotal link keeper for securing the head end of thespur. Fig. 7 is a sectional view of the lower part of the compositeshank, showing the removable spur therein, and the position of thepivoted keeper link securing the head of the spur. Fig. 8 is across-section of the lower portion of the shank which receives the footof the wearer, and illustrated the inner flanges constituting a grooveor seat for the spur.

Other than Fig. 1, all figures are full size.

Throughout the drawing and description the same number is used to referto the same part.

Considering the drawing, the shank of the climber is made up of the twinflanged members 1 and 2 united or may be one T iron unit with theprojecting flanges 4 and 5 in contact as shown in Figs. 4 and 5, thelatter section being taken on the broken line 5--5 of Fig. 3.

Fig. 2 shows a front view of a flat piece termed for the purpose of thisdescription the leg plate 6. The edges 7 and 8 of the plate are turnedover as best shown in Fig. 5, upon a second plate 9 which is given araised portion lengthwise to movably receive the upper portion of theshank. The

raised portion or slide housing is marked 10. The back or fln of theplate 9 marked 11 in Fig. 1 has a longitudinal slot 12 for the usual legstrap of the wearer not shown. Holes 13 are made through the fin of theplate 9, and through the meeting flanges 4 and 5 of the flanged members1 and 2, and a cotter pin 14 may be passed through either hole 13. Theleg plate 6 can be thus adjusted longitudinally of the shank which ismade longer or shorter thereby as will be readily understood.

Considering Fig. '8, numbers '15 and 16 mark widened lower parts of theflanged members, and the inner and slanting flanges 17 and 18are'combined to form a groove or seat for the spur 19, curved incorrespondence with the foothold part of the shank. The spur point is:marked 20. On the left hand side in Fig. 7 are shown two pins 21 and 22fast in-the shank, and a third pin is carried by the end of the shank atthe right side of Fig. 7. The spur has a hookhead 24 arranged to engage'the pin 23, and notches '25 and 26 to engage the pins 22"and 21. Asbest shown in Fig. 6, the end 27 of the lower shank portion 15, andtheend 28 of the shank part 16 carry the pin 23 that engages the spur hookhead 24. 7.0

In Fig. 7 it will be understood that the hook head 24 of the spurengages the pin 23 between the ends marked 27 and 28 in Fig. 6, and aspace 29 is shown in Fig. 6 between those ends for the introduction ofthe head 24. A keeper link 30 swings with the arrow indicated, and ithas an off-set back rib 31. This construction leaves a space between thelink and the rib for the usual straps common to pole climbers. The riband the link at the bottom are joined by an integral cross-head 32, andit is this feature that bears upon the head 24 to hold the spur.

In the operation of removing the spur, if the link is swung to the rightas indicated in Fig. 7 the head of the spur is free, and the spur maynow be passed outwardly between the two pins 21 and 22 thereby freeingthe spur from all the pins. When the spur is in position as illustratedin Fig. 7 and the usual strap, not shown, is passed through the space 33and secured around the ankle of the wearer, the keeper link cannotswing, and the spur is held absolutely against displacement. It will beunderstood that the spur may be removed to sharpen its point when neededor different length spurs may be carried to replace the spur on theclimber as per requirements of the operator in climbing different gradesof trees or poles. This invention is not limited to the exact shape orsize of any element of the combination, as the individual features mayclearly be made in difierent forms.

Having now described this invention, I claim:-

1. In a linemans climber, the combination with a shank portioncomprising twin flanged members secured together or a T iron unitforming the shank of the climber, said shank portion having a lower partfashioned to receive the foot of the wearer, a removable spur engagingsaid lower part of the shank, the said members having inner flangesformed to seat the said spur, and means for securing the spur.

2. In a linemans climber, the combination with a shank portioncomprising twin flanged members secured together or a T iron unitforming the climber shank, of an adjustable leg plate, means forsecuring said plate at the upper end of the shank, a removable spur,said shank portion having a lower part constructed to receive the footof the wearer, andmeans for securing the spur to the said lower part ofthe shank.

3. In a linemans climber, the combination with a shank portion, saidshank portion having a lower part fashioned to receive the foot of thewearer, a removable spur engaging the lower part of the shank, and meansprovided with an opening for the passage of a strap and constructed tosecure the spur in detachable relation to the said lower part of theshank.

4. In a linemans climber, the combination with a shank having a lowerpart fashioned to receive the foot of a wearer, of a removable spurconstructed to correspond in curvature with the said lower part of theshank and to engage the shank in detachable relation, means for securingthe spur comprising a pivoted keeper having an opening for the passageof a strap.

5. In a linemans climber, the combination with a shank having a lowerpart fashioned to receive the foot of a wearer, of a removable spurconstructed to correspond in curvature with the said lower part of theshank and to engage the shank in detachable relation, the said spurhaving at one end spaced notches, the said shank having spaced pins forengaging said notches, said spur having at the other end a hook head,said lower part of the shank having near its end a pin arranged toengage the said hook head of the spur, and means for securing the headof the spur to the end pin of the shank.

6. In a linemans climber, the combination with a shank comprising twinflanged members secured together, the said composite shank having alower part fashioned to receive the foot of the wearer, of a removablespur constructed to correspond in curvature with the said lower part ofthe shank and to engage the shank in detachable relation, said spurhaving at one end spaced notches, said shank having spaced pins forengaging said notches, said spur having at the other end a hook head,said lower part of the shank having near its end a pin arranged toengage the said hook head of the spur, and means for securing the spur.

7. In a linemans climber, the combination with a shank having a lowerpart fashioned to engage the foot of the wearer, of a removable spur,said shank and spur having mutually engaging devices for securing thespur at one end of the spur, said spur having a hook head at the otherend, said lower part of the shank having near its end a pin arranged toengage said hook end of the spur, and means pivotally carried by saidend pin of the shank and provided with a strap opening and having across-head adapted to engage and release the hook head of the spur.
